Abstract: Earthworms are the soil dwelling invertebrates, which have great agricultural importance, they influence the soil structure by ingestion, which leads to the breakdown of organic matter and its ejection as a surface or subsurface cast. The 3545DQ effect of the chemicals on earthworms depends on the used substance, but regardless the substance nature, it must be considered in the ecological risk assessment both the direct and the indirect effects of it on soil life. The effect of selected pesticides on the earthworm E. fetida its survival and reproduction are estimated in this research. Some parameters such as changes in the density, mortality, biomass, hampered life activity and the number of laid cocoons and hatching are evaluated. Selected pesticides contained the following active chemical compounds: the type of pesticides used is Glyphosate (Round - up) (herbicide), Chlorpyrifos (Salute) (insecticide). We found that, earthworms responded to soil pesticides in different ways. Round - up caused were greater than that of control mean body weight and Salute similar that of control mean whereas, The Ru seems to have greater impact on the juvenile production whereas, Sal has low effect on the juvenile production. This work will be helpful for future evolution of soil ecological.
